    摘要： The invention provides a package which varies the tension within a fiber Bragg grating (or other fiber-based optical device) by resilient deflection of a fiber support member through differential thermal expansion, thereby allowing the temperature/tension characteristics of the package to be tailored so as to provide the desired optical characteristics throughout a wide temperature range. The fiber tension/temperature correlation may be tailored using the linear coefficient of expansion of two different materials, by varying the resilient flexibility of a beam supporting the fiber, by varying a length of an arm extending from the beam to the fiber, by varying the resilient strength of the arm, and the like. By relying on the resilient deformation of a flexible fiber support structure, the present invention provides a large number of degrees of freedom within the package design parameters. Where such precise control over the temperature/tension correlation is not required, the invention provides alternative compensation packages which can be mass-produced easily.

    摘要翻译： 本发明提供了一种通过差动热膨胀使纤维支撑构件的弹性偏转来改变光纤布拉格光栅（或其它基于光纤的光学装置）内的张力的封装，从而允许对包装的温度/拉伸特性进行定制 以便在宽的温度范围内提供期望的光学特性。 纤维张力/温度相关性可以通过使用两种不同材料的线膨胀系数进行调整，通过改变支撑纤维的梁的弹性柔性，通过改变从梁到纤维延伸的臂的长度， 臂的弹性强度等。 通过依靠柔性纤维支撑结构的弹性变形，本发明在包装设计参数内提供了大量的自由度。 在不需要对温度/张力相关性的精确控制的情况下，本发明提供了可以容易批量生产的替代性补偿包装。

    摘要： The present invention provides an improved clip for supporting an end of an optical fiber relative to a mount surface. Typically, a sleeve is disposed over the optical fiber adjacent to its end. The clip comprises a clip body having upper and lower surfaces with a flange disposed adjacent to the lower surface. The flange is affixable to the mount surface, and walls extend from the upper surface of the body to define a channel at which the clip is affixable about the sleeve. Advantageously, when the sleeve is affixed within the channel, the body rigidly couples the sleeve to the flange, thereby avoiding misalignment between the optical fiber and any optical device which is on or supported by the mount surface.

    摘要： The shock tube comprises a tube, a first electrode, a second electrode and a stopple, wherein the tube is internally provided with a cavity for accommodating a target liquid sample. The first electrode is arranged at one end of the tube. The second electrode is arranged in the stopple, and the outer end of the second electrode can be electrically connected with the exterior via an opening of the stopple. The stopple is internally provided with an elastic piece connected with the second electrode. The outer side of the elastic piece is connected with the stopple, and the inner side of the elastic piece is connected with the second electrode. The invention further provides a cell electroporation device where the shock tube can be placed.

    摘要： Provided is a method applied to a system including a plurality of sensors, a proxy, and a server. The method includes: measuring objects by the plurality of sensors to obtain first measurement values; computing a correlation among the first measurement values by the server based on the first measurement values; computing an actual measurement value of a second measurement value by the proxy based on the first measurement values and a given function; verifying the plurality of sensors by setting one or more sensors as verification target sensors in turn by the server at predetermined timing; computing a predicted value of the second measurement value by the server based on the correlation and the first measurement values obtained from the other sensors; and outputting the predicted value of the second measurement value instead of the actual measurement value thereof at least during the verification of the verification target sensors.

    摘要： In a switching regulator control circuit according to aspects of the invention, a drain current is converted to a voltage Vis with a resistance. The voltage is delivered to a multiplication circuit. The multiplication circuit generates and outputs a voltage that is a product signal of the voltage and a voltage that is proportional to a duty factor. A comparator circuit compares the voltage with an error signal delivered to the other comparison input terminal of the comparator. When the voltage has reached the error voltage, the comparator delivers a turn-off instruction through an OR circuit to a terminal of a flip-flop.

    摘要： A regular expression matching method and system, and a searching device are provided. First, the searching device performs string filtering on a data stream to be matched, in which if keywords in the data stream and preset character words have at least one same character, the searching device indicates that the data stream passes through the string filtering. Then the searching device performs regular expression filtering on the data stream passing through the string filtering. In a string filtering process through the method, system, and device, when Hash mapping positions of the keywords of the data stream are a subset of the Hash mapping positions of the character words, it indicates that the data stream passes through the string filtering, and it is not required to store the keywords and further compare the keywords with the character words, thereby saving the storage space and improving performance.
